Excerpt from Mineral Deposits of New Jersey and Eastern Pennsylvania The Lehigh Valley is the largest producer of slate and cement in the country, and the conditions represented at the different quarries and the methods used in handling these substances are representative of the best American practice. One of the anthracite basins will be touched at Lansford, Pennsylvania. Opportunity will be given to see the complicated structural features of a mine where stripping has been practised on a large scale and where the famous Mammoth coal seam is exposed. Opportunity also will be given to observe the methods of underground working. The iron deposit at Cornwall is an especially fine exhibit of a replacement body of magnetite, clearly associated with igneous intrusion and related activity. The open-pit method of working has exposed the major structure, and virtually the whole range of mineral and rock product can be seen in the open. Opportunity will be given at all these places to gather samples of typical material. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
